Surface and interface engineering have shown broad application prospect in energy conversion. Mo 2 C-C/Sb 2 S 3 composites have been synthesized by coupling Mo 2 C-C composites and Sb 2 S 3 nanowires with coupling agent. The performance of the devices has been investigated. Under irradiation by light source, the device showed better electrical contact, fast response speed (rise time 0.135 s, decay time 0.132 s) and larger on/off ratio ( 1 . 5 × 1 0 2 ) than the device which assembled by mechanical mixing ( 1 × 1 0 2 ) and pure Sb 2 S 3 nanowires (47), respectively. The performance has been enhanced by modifying the surface and interface of materials. This approach provides a new idea to enhance the high-performance photodetectors and other inventive optoelectronic devices.

The interface compatibility lies in the heart of present investigations on solid-state batteries, now facing significant challenges in practical use. The non-coherent interface structure with the underlying complex electrochemical processes evolves dynamically to pregnant the unfriend seeds to degrade the battery performance. Therefore, interface engineering (or control) in solid-state batteries gives birth to a new theme as ‘the interface is equal to the battery’. In this context, a facile but robust technique is proposed here by smoothing the Li 1.5 Al 0.5 Ge 1.5 P 3 O 12 (LAGP) ceramic pellet with a mirror-like surface, which is found operational in running a solid battery in unprecedentedly a thousand cycles with capacity retention of 80% at 0.5C, 50 °C. Such an unconventional operation is, as a matter of fact, largely decreasing the physically interface contact but proved powerful in guiding the Li-ion homogeneous deposition. Moreover, the self-generated LiF involved interphase layer works efficiently to dynamically balance structural and electrochemical stabilities, where the LiF is introduced by the in-situ polymerization of tiny liquid electrolytes. Hence, the profound results draw the incompatible interface issues forth to the component adjustment of interphases, namely in search for rational descriptions to connect the solid-state electrolyte and electrodes, which probably holds the key to unlocking the high energy density solid-state batteries.

Chemical doping of boron atoms is essential to modify the electrical properties of graphene films. The synthesis of large-scale boron-doped graphene with high uniformity and good electrical properties is still a great challenge. To improve the quality and uniformity of boron-doped graphene, we introduced several methods to engineer the surface of the copper catalyst for chemical vapor deposition. The ethylic acid treatment proved to be more effective to remove surface impurities than the hydrochloric acid treatment. Moreover, electrochemical polishing showed the best performance in reducing the impurities and surface roughness in all the methods. The sheet resistance and carrier mobility of the boron-doped graphene film grown on the electropolished copper foil were 2.35 kΩ/□ and 1.15 × 103cm2·V−1·s−1at room temperature, respectively. Our results suggest that the boron-doped graphene grown on the electropolished copper catalyst possesses a high carrier mobility and less structural defects, which makes it suitable for application in optoelectronics.Keywords:boron-doped graphene;surface engineering;electrochemical polishing

The widespread application of epoxy resin (EP) is limited by its inherent high fire hazard, primarily attributed to its substantial release of heat and the generation of toxic byproducts during combustion. The usage of 2D material of titanium carbide (MXenes, defined as MX) has been confirmed to show potentials in flame retardation. However, the flame-retardant efficiency of MX is relatively-low. Thus, the interfacial engineering strategy is employed for in-situ development of MoS 2 nanoflakes on MX surface, acquiring the product of MX@MoS 2 , which shows the higher interfacial interaction with EP matrix and dispersion stability. By only using 1.0 wt% MX@MoS 2 , the PHRR and THR are obviously decreased by 35.8 % and 38.0 %, respectively. Notably, the addition of 3 % MX@MoS 2 results in a higher PHRR reduction 49.4 %. Meanwhile, the PSPR and TSP have reduced by 48.6 % and 36.9 %. Such results indicate the enhanced flame retardance, benefiting from the physical barrier and chemical catalyst roles of MX@MoS 2 . Of note, the peak CO and CO 2 yields are decreased by 53.3 % and 57.2 %. Upon exposure to heat source, MX@MoS 2 promotes the formation of dense, thermally-stable char layer, which effectively insulates the underlying polymer, slows down thermal and material transport, and impairs the volatile emissions. It is satisfying to find that the mechanical characteristics of EP composites are enhanced after adding MX@MoS₂. This study offers ideas to produce an extremely efficient MX-based flame retardant, extending the applications of composites made of polymers.

Photocatalysis is believed to be an important way of reducing NO pollutant in air and the facet engineering of semiconducting oxides could enhance the efficiency of the photocatalysis. ZnO nanoparticles with different exposed crystalline facets were successfully synthesized using a hydrothermal method and their photocatalytic degradation towards NO was investigated. The crystals from ZnCl 2 precursor were hexagonal mesoporous ones with exposed (0002) facet, while those from zinc acetate were in the form of flakes or wheat ears with enhanced exposure of (10 1 ( − ) 1) facet. Calcination in air imparted an enhanced the textural coefficient of the orientated facets as well as the oxygen defects. The nanocrystals with enhanced (0002) facet and lower flat-band energy did better in photoelectrochemical water-oxidation than those with exposed (10 1 ( − ) 1) facet that showed superior photocatalytic activity (approaching 76.7 ± 0.6% under 365 nm photons) for NO oxidation. According to theoretical calculations, (10 1 ( − ) 1) facet with O termination showed much higher affinity to NO molecules than other configurations, and the oxygen vacancy in ZnO played an minor role in the photocatalytic oxidation of NO. A high quantum efficiency approaching 97.5 ± 1.4% under 275 nm photons was obtained for the ZnO crystals from zinc acetate with mixed (0002) and (10 1 ( − ) 1) facets. This research explores the special characteristics of ZnO with different exposed facets and is important for the future design of highly efficient photocatalyst for hazardous material removal.

Crystal facet engineering is an important concept in material science but is yet to be explored direction of fabricating catalysts with improved selectivity. In this study, we prepared pure TiO 2 brookite nanorod catalysts exposed with a variation of (120), (111), and (110) active crystal domains for photocatalytic NOx (nitrogen oxides) abatement using TALH (C 6 H 18 N 2 O 8 Ti) titania precursor via a variation of sodium lactate (C 3 H 5 NaO 3 ) and urea (NH 4 CNO) addition. The different characterization such as XRD, SEM, and TEM proved the high availability of (111) crystal facet and approximate equal presence of (120), (111), and (110) crystal domains in TALH-6U-SL resulting in up to 4.9-fold higher selectivity than commercial TiO 2 -P25 as well as other brookite nanorod catalysts. TGA, FTIR, and XPS results demonstrated that compared to other catalysts, TALH-6U-SL nanorod catalyst adsorbs more water and contains more oxygen vacancies and crystal defects, thus boosting the photocatalytic selectivity for NOx conversion to NO 3 − ions.

Designing and fabricating nanozymes with photoactivity for CO 2 reduction poses a significant challenge. Here, a hierarchically structured ZFs-tpyNi heterojunction nanozyme, comprising a terpyridine-based Ni complex supported on ZrO 2 nanoframes, has been created through an interfacial engineering strategy for efficient CO 2 reduction under visible light. Due to its unique structural and compositional advantages, ZFs-tpyNi demonstrates superior photocatalytic CO 2 -to-CO conversion compared to its counterpart of ZFs and tpyNi, achieving a CO yield of 18.2 µmol and a selectivity of 92.4 % with a high apparent quantum efficiency of 0.96 % in 3 h. These innovative catalysts also show excellent durability for at least eight cycles without a loss in performance, maintaining a remarkable structural stability with no obvious collapse of its framework and morphology. Systematic investigations reveal that ZFs-tpyNi heterostructures exhibit a high specific surface area advantageous for the effective loading of tpyNi and exposure of active sites. The robust ZFs framework, characterized by extensive porosity, prevents nanoparticle agglomeration and accelerates mass transfer during catalysis. Additionally, the spatially heterogeneous interface enables precise modulation of band alignment and bandgap dynamics in nanozymes, enhancing light absorption and promoting the generation and separation of photogenerated charge carriers. Consequently, the nanozyme demonstrates enhanced CO 2 adsorption and activation capabilities, leading to improved selectivity of catalytic products. This work aims at highlight the role of nanozyme catalysts in sustainable energy production.

The unprecedented pandemic has highlighted the need for textiles that rapidly inactivate pathogens to protect public health. However, how to achieve rapid, effective and durable pathogen inactivation with the minimum antimicrobial dose loading has become a major challenge for cotton fabric modification. Here, a surface engineering cotton fabric (Co-CMC@Cu 2+ ) was prepared by grafting carboxymethyl chitosan (CMC) onto cotton fabric and then loading with Cu 2+ via coordination. The Co-CMC@Cu 2+ with minimal copper ion dosage achieved rapid inactivation, excellent comfort, good biosafety, and durability. Specifically, Co-CMC modified with 12.5 mmol/L copper ion solutions achieved impressive bacterial reduction (BR) rates of 94.3 % and 89.3 % against E. coli and S. aureus , respectively, within 10 min of contact. Moreover, the bacteria were completely eradicated after 2 h of continuous contact. Additionally, Co-CMC@Cu 2+ achieved excellent phage reduction (PR) rates of 98.9 % and 100 % against phi6 and phi-x174 bacteriophages, respectively, within 30 min of exposure, highlighting its potential for viral inactivation. Furthermore, Co-CMC@Cu 2+ demonstrated exceptional durability for pathogen inactivation, with BR and PR values above 80 %, even after 150 washing cycles. This novel antimicrobial and antiviral cotton fabric will be a promising candidate textile to protect public health during a pandemic.

Electrochemical urea synthesis has recently emerged as a fascinating energy-efficient alternative route, while it remains challenging to achieve simultaneously high production rate and Faradaic efficiency. Herein, we realize an energy-favorable electrochemical C-N coupling path through CO 2 and NO 3 − co-reduction at the heterointerfaces of Cu/Cu 2 O microparticles, generated by in-situ electrochemical engineering on bulk Cu 2 O. We achieve urea production rate of 632.1 μg h −1 mg cat. −1 with a corresponding Faradaic efficiency of 42.3% at −0.3 V (versus RHE) under ambient conditions. Operando synchrotron radiation-Fourier transform infrared spectroscopy, along with theoretical calculations, reveals the coupling of intermediates NOH* and CO* at the heterointerfaces, benefiting from the modified electronic structure. This work provides a practical route for catalyst design and insights into urea electrosynthesis systems.

Steering selectivity in photocatalytic conversion of CO2, especially toward deep reduction products, is vital to energy and environmental goals yet remains a great challenge. In this work, we demonstrate a facet-dependent photocatalytic selective reduction of CO2 to CH4 in Cu-doped TiO2 catalysts exposed with different facets synthesized by a topological transformation from MIL-125 (Ti) precursors. The optimized round cake-like Cu/TiO2 photocatalyst mainly exposed with the (001) facet exhibited a high photocatalytic CO2 reduction performance with a CH4 yield of 40.36 μmol g–1 h–1 with a selectivity of 94.1%, which are significantly higher than those of TiO2 (001) (4.70 μmol g–1 h–1 and 52.6%, respectively), Cu/TiO2 (001 + 101) (18.95 μmol g–1 h–1 and 69.6%, respectively), and Cu/TiO2 (101) (14.73 μmol g–1 h–1 and 78.9%, respectively). The results of experimental and theoretical calculations demonstrate that the Cu doping dominating the promoted separation and migration efficiencies of photogenerated charges and the preferential adsorption on (001) facets synergistically contribute to the selective reduction of CO2 to CH4. This work highlights the significance of synergy between facet engineering and ion doping in the design of high-performance photocatalysts with respect to selective reduction of CO2 to multielectron products.

Doping and interface engineering are both pivotal strategies for enhancing the selectivity of CO 2 reduction catalysts. However, as these strategies have often been explored independently, the question of which is more effective or whether their effects can be synergistically combined remains open. Given that doping and interfaces serve as crystallographic defects, they can be engineered to coexist within the same crystal structure. In this study, we strategically introduced both defects into a copper catalyst by modulating the indium content during crystal growth. Our investigation into the electrochemical performance of these catalysts for CO conversion reveals that while doping consistently enhances conversion selectivity, the presence of Cu/In interfaces disrupts this trend. The most promising catalyst, with 3% indium doping, demonstrated an impressive CO selectivity of 95.38±1.5% and a partial current density of -2.25 mA cm - ² at -0.8 V vs. Reversible Hydrogen Electrode (RHE). This research provides critical insights into the complex interplay between doping and interface engineering, offering a new pathway for the rational design of highly selective CO 2 reduction catalysts.

Heterostructure materials are increasingly utilized in solar energy conversion to pursue high efficiency and long-term stability. The charge transfer across interfaces gives rise to major energy loss arising from non-ideal interfacial effects, i.e., high interfacial energy barrier and low interfacial contacting area. Herein, we demonstrate a facile interface engineering strategy to eliminate non-ideal interfacial effects. A heterojunction of CN@C-P25 is constructed via polyphenol-assisted assembly of titania (P25) and carbon nitride (CN). The uniform dispersion of P25 on CN enlarges the interfacial contacting area of 3.2-fold compared with random dispersion, while the transformation of polyphenols into conjugated carbon facilitates the interfacial charge transfer by switching a 0.4 eV Schottky contact to a 0.1 eV Ohmic contact between CN and P25. A 2.5-fold enhancement of charge transfer flux is obtained with an initial reaction rate of 5185 μmol h −1 g −1 for photocatalytic nicotinamide regeneration.
